.T0 all whom it may oon/cern:

Be it known that I, JOHN R. LONG, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have in- Ven ted certain new and useful Improvements in Pipe-Vises; and I do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in pipe-vises; and the invention consists in the construction and combination of parts substantially as shown and described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a longitudinal sectional elevation of the vise on a line corresponding toY Y, Fig. 2. Fig. 2 is a plan View of theA vise with a portion at the left in section. Fig. 3 is a cross-section of the vise on a line corresponding to X X, Fig. l, looking toward the left.

In the constructiony thus shown Arepresents the base or bracket-support by which the vise is adapted to be attached to a wall or post or such other supporting medium as may be found convenient at the place where the vise is to be used, and to this end the said base or support is provided with a perforated bottom extension adaptedto be engaged by screws or bolts to fasten it in place. rlfhis renders this particular form of vise convenient for taking into buildings incourse of construction and attaching here or there, as a plumber may find advantageous and as he may have occasion on different floors.V Otherwise the said part a might be constructed to rest down upon a work-bench or other rest in a stationary position; but this is not the idea of the present vise, which is further provided with a collar or casing a of tubular outline at right angles to the depending arm or flange o.' and set o at one side thereof at the top, as clearly seen in Fig. 3, thus taking the working part of the-vise away fromits support.

B represents the single jaw member of the vise, which has a barre1-shaped portion b, adapted to enter into the collar or casing a from one end, as shown, and is provided with an annular shoulder 2, which engages against one end of collar ct and limits the endwise movement of member B, as will hereinafter more clearlyappear. The saidjaw member is hollow or tubular in its barrel portion and has a solid head 3 atits front end and is provided With an opening'into its interior at its bottom in the neck of said head for the entrance and operation of clamping-chain O. Aiiixed to the side of said head are steel jaws D, which are screwed or bolted to head 3 and abut against shoulders 4 at their rear edge. The engaging edges of the said jaws are substantially V-shaped and are provided with teeth or serrations 5, as seen in Fig. 1. The body of the jaw member itself is preferably made of'cast metal and of such weight and size as its use may demand, and I build different sizes, according to use, because this vise, as already indicated, is a portable article and intended to be carried from place to place for job-work on the ground. To these ends this vise is provided also with a single adjustment rather vthan more, and the jaw member B can be rotated or turned round and round in the casing or support a, so that a pipe may be held in either a horizontal plane or in a perpendicular plane or at any angle, as may be found necessary.'

G represents a screw which is threaded at one end and has the chain O pivotally con# uected with its opposite end within the jaw member B, relatively as seen in Fig. l, and the said screw is supported in its working position by cap or head H, which is shouldered i into and set against one en d of casing or collar a and loosely bolted or screwed to the adjacent end of jaw member B, Fig. 2. It is not designed to have any considerable play or unnecessary freedom between the cap and barrel connected by screws 6, but there needs to be enough looseness to afford free rotation of the jaw member in its support, as well as to clamp against both ends of barrel b when it is otherwise disengaged, as hereinafter described; but there is no rectilinear movement of said member in the base. The said screws 6 serve the further purpose, also, ofholding the cap H in its proper relation tothe other parts, thereby giving a positive support, to screw G; but the said cap is'no't threaded where the screw passes through, and the screw carries an actuating sleeve or nut J, which bears against cap H and is provided with a handle L for turning it. It follows IOC that screw G does not turn as in vises generally, but travels in a direct line without rotation when the parts are tightened or loosened, while nut .I turns on the screw and bears against cap H.

Chain C is double-linked with pins c at the joints of its links, which extend laterally on both sides a suflicient distance to engage lugs '7 on the top of head 3 of the jaw member. These lugs are spaced apart to permit the chain to pass between them, and each lug has a vertical slot 8 on its inner side adapted to be engaged by the extremities of one set of pins c, while another set engages against the rear edges of the lugs, so that when the chain is held for work both sets of pins take the strain.

Now assuming that a pipe P is gripped in the vise, as shown in Figs. l and 2, and nut J is tightened it follows first of all that annular shoulder 2 on jaw member B will rest hard against the adjacent end of collar-casing a and frictionally lock and hold the said jaw member from further rotation while the locking continues. In this operation cap H is of course forced with equal firmness against the outer end of the said easing, and the tighter the parts are drawn up the firmer is this locking made. Thus also is the pipe P engaged in the jaw member by means of the chain C, and as the two jaw-plates D are spaced apart relatively, as shown, with the chain between, the pipe is very firmly gripped also from twisting or turning in the jaws. Chain C is supposed to have sucient length to let it out for the largest pipes, and in engaging a pipe the chain is iirst drawn as closely as it can be conveniently by hand around the pipe and locked on lugs 7, and then further tightening of the parts is eected by screwing up the parts. A nut 10 on screw G prevents sleeve-nut Jfrom running od the end of said screw.

In a sense cap H is incorporated with barrel b of the jaw or jaw member, but is separable therefrom, and whatever pressure comes upon said cap from nut J bears against the end of sleeve or bearing a on base A, while at the other end shoulder 2 bears against the said sleeve. Clearly this calls for a measure of looseness or freedom between cap H and barrel Z), or they could not both lock against the ends of the sleeve b at the same time and by reason of the sameV pressure.

Screw G has been described as being itself non-rotatable, and so it is in tightening or loosening a pipe; but when jaw B is bodily rotated in the base or casing the said screw and the parts thereon, with cap H, rotate also in like manner and degree. The lugs 7 for engaging the chain are therefore necessarily on the jaw or on a part to rotate therewith and cannot be on .base A if rotation of the jaw is to be had bodily about its axis therein, as shown. For this reason also the lugs 7for engaging the chain are inclined rearward somewhat, and thus the jaw may be turned with said lugs below7 and still hold the chain. The portion b is referred to also as being tubular, and bythis I mean that it has a cylindrical exterior and is open axially for the introduction of screw G and making connection therein of chain C. If the bearing b were shorter than here shown and otherwise substantially the same, it would still be regarded as tubular.

Part J is generally referred to herein as a nut, and it may have the form of a sleeve, spool, collar, or any other form or shape, and it may have av sliding or a rigid handle, as may be preferred. As here shown, the handle is set at one side of the nut and adapted to slide, as is common in bench-vises.

Part H is shown and referred to as a cap, and so it preferably is; but it might not cover the entire end of bearing b and yet serve my purpose and serve practically as a cap or closing part, and for this reason this term is retained and is understood as being as broad as this interpretation.
